Twitter is "no longer a tool that's accelerating science. On the contrary," said Michael Mina, chief science officer at eMed and a pediatric immunologist who regularly used Twitter during the pandemic to talk about COVID.
He still uses Twitter, but sparingly, and expects he'll leave completely within the next six months, he said."
It allowed me to effectively and efficiently sift through the noise of this massive explosion of new publishers and journals and papers that were published," Mina told Axios."That has gone away. It's now another big noisy mess," he said, adding he no longer gets pointed to relevant experts while those with the most polarizing content get promoted and discourse is drowned out.
Twitter did not respond to a request for comment.
The big picture: Since Musk acquired Twitter last year, the company has made cuts to its trust and safety staff, restored accounts of users banned for spreading misinformation and removed the platform's system for verifying trusted accounts.
In comments to Axios as well as online, scientists and medical researchers have said they're increasingly finding it difficult to find relevant information on Twitter. A recent study found Twitter's new algorithms are amplifying anger more since Musk took over the platform.
Hotez told Axios he's seen a clear shift in anti-vaccine views as part of a well-organized, well-financed anti-science movement, and that's playing out on the platform.
Others say the platform has at times become "scary" for many health professionals amid anti-science rhetoric. That's particularly the case for women and people of color, Caballero said.
What to watch: Several Twitter alternatives are emerging but it's not clear which, if any, will become the new platform of choice for scientists.
Experts often point to Mastodon, Bluesky and Meta's planned Twitter rival as possible options. Many scientists have been publishing elsewhere for a while on platforms like Substack.
Caballero suggested the future may be in a "decentralized" social media platform that mirrors the distribution model of podcasts, which have platforms such as Spotify and Apple.
Online research-sharing could shift to a less public model, Mina suggested.
